摘要
本文通过对城市污水纳污海区沉积物样品释放有机物的研究,初步揭示了沉积物释放耗氧有机物(COD)的一般规律。研究表明宁波海域沉积物释放COD的范围在0.15×10-3~0.80×10-3之间,释放速率平均为103.9mg/(m2.d);舟山沈家门附近海域沉积物释放COD速率平均为253.1mg(m2·d)。沉积物释放COD的量与沉积物中有机质的含量成正比,而其释放速率与沉积物有机质的含量关系不大。
The rule of sediment release COD is discussed in the paper. The results show that thecontents of release COD(RCOD)of sediment in Ningbo sea area is about 0. 15 × 10-3 to 0. 80- 10-3 And the rate of RCOD in this area is about 103. 9 × 10-3 mg/ (m2. d).
